North Sails WS Jambor ULTIMATE RDM

Tow Preg  Tow-Preg lays a matrix of fibers around the mandrel mechanically, meaning all fibers are continuous over the length of the mast. Every fiber is identical and wall thickness is kept consistent. This results in a lighter and faster response rate mast without any weaknesses or breaking points.

Mushroom Sand Stopper  An oversized foam plug, mushroom style, is placed on the top of all mast bottom pieces and extensions, cleaning the sand from the top piece prior to inserting the bottom piece, and keeping the sand out during sailing. As a result, just like magic, you have a sand-free and frictionless connection between your rig components. Getting components blocked together due to sand, is now a distant memory.
